SASI-I WEIGHT.

Application filed December 12, 1923.

To all whom t may concern',

Be it known that I, JOAH BRoGDnN, a citizen of the United States,residing at Melrose Park, county of Montgomery, and State ofPennsylvania, have invented certain new andV useful Improvements in Sashlllleights, whereof the following is a specication, reference being hadto the accompanying drawings.

My invention relates to sash weights such as are -use'd fin connectionwith window structures wherein the two sashes are balanced by a singleor common weight at each side of the window, the sash cords or chainsbeing attached at their opposite ends to the respective sashes, and theweights suspended in saddle loops formed at the points of retroversionof the oppositely moving runs of the cords or chains.

Amongst the objects of my invention are to enable weights useful for thepurpose noted -to be easily adjusted for balancing sashes of differentsizes; and to insure such weights against turning or wobbling within theweight boxes afforded by the window frame so as to prevent the chains orcords from becoming deranged or twisted.

These, together with other objects and attendant advantages of thisinvention, will become readily apparent from the detailed descriptionwhich follows of va typical embodiment thereof; while the appendedclaims define the scope of said invention in so far asvpresent knowledgeis concerned.

In the drawings Fig. I is a perspective view of a window structure ofthe type in which a weight embodying thisV invention may beadvantageously employed.

Fig. II is a sid-e elevation of the improved sash weight, on an enlargedscale.

Fig. III is an end elevation of the sam."U

viewed from the right of Fig. II., v

Fig. IV is a horizontal plan section taken as indicated by the arrowsIV-IV in Fig. II.

Fig'. V is a perspective view of the upper portion of the primary ormain weight member of the device; and

Fig. VI is a similar view of one of the supplemental weights capable ofbeing used, in an auxiliary capacity, with the primary or main weightmember aforesaid.

In these illustrations, the improved sash weight is comprehensivelyindicated by the Serial No. 680,074.

numeral l and shown vas comprising a primary or main we iglit member 2,and a series of auxiliary weight members 3 adapted to be superposed uponthemember 2 as best shown in F ig. II, the number of auxiliary weightmembers employed being determinedin accordance with the size of thesashes with which the sash weight l is to be used. More especially fromFigs'. IV and V, it will be noted that the plan cross sectionalconfiguration of the weiglit member 2 is oblong with its ends wellrounded so as to render insertion into the weight box or channel 4 ofthe window frame easy of accomplishment, and to avoid sharp projectingcorners likely to increase frictional contact with the side walls ofsaid weight box or channel. Across its top, the member 2 has alongitudinal slot 5 extending downwardly to a level indicated at 6. Thisslot 5 is provided for accommodation of pulleys 7 7, which are mountedupon `fined axles 8-8 occupying positions in a common horizontal `planeas clearly shown, so as to predetermine alignment of said pulleys, withtheir peripheral grooves in direct registry. The axles 8-8 of thepulleys 7 7, it .will be observed, are in the form of screw bolts headedat one end as at 10, and provided with detachable nuts ll at theopposite ends, the side walls of the primary weight member 2 being'recessed as shown `at 12e-12 (see Fig. IV) foi.l lodgment of the heads10 and nuts 1l of said bolts. In this way all surface projections areobviated so that .a continuous flush surface of the weight l ispresented to the. side walls of the weight channel 4f of the windowframe.

The sash cord or chain indicated at 13 may be of any approved form orconstruction, and, as will be apparent from Fig. I, has its oppositeends attached to the respective sashes 14-15. This cord or chain 1Spasses about the conventional sheaves 1.6 appropriately supported nearthe top of the window frame, and from thence has its opposite runsextending vertically downward in the weight box or channel 4 to a pointof retroversion where it passes beneath the pulleys 7-7 in the mainweight member 2 and thereby supports the same freely in suspensionwithin the saddle loop thus formed. By this arrangement it follows that,as the sashes 14--15 are moved, the weight l will correspondingly shiftits position Without any tendency Whatever to turn, or wobble Within thebox or channel t of the Window frame, the definite guidance thusvafforded precluding the possibility of any noises Whatever accompanyingthe sash shifting.

Coming now to the examination of the auxiliary Weight members 3 of whichone is shown in perspective in Vl, attention is directed to the factthat they are generally of the same configuration as that of the..mainor primary Weight member 2, and differ from the latter' only as todepth. The lower faces of said auxiliary Weight members 3 are rprovidedwith longitudinally extending ridges 17 adapted to engage with`Correspending slots 17'ZL in adjacent ausiliary Weight members, orWithin the top of thefslotr 5 of the primary Weight member i?,suilicient clearance being` left above the pulleys. 7 for this purpose.ln addition, the auxiliary Weight members 3 are characterized by otherridges 18, preferably of Vfshaped cross-section, as best shown inlfig.V1, extending laterally of the longitudinal ridges 17 and designed toengage correspondingly configured recesses 19 in adjacent auxiliaryWeight members 3, or With similar recesses 2O in the top of the mainWeight member 2. By reason of such complementary longitudinal andlateral ridgingl and recessing,` it will be at once apparent that theseauxiliary Weight members 3 may be inten changeably used in connectionwith each other and also with the main or primary Weight,.2vand thatthey are interlocking already been said, and therefore requires nofurther detailed descriptiointhis being also true of the advantages,both structural and commercial, accruing from the novel constructionherein set forth.

Having thus described my invention, l claim:

1. In a sash v-Jeight` the combination of a main Weight member, a pairof pulleys, having their axes in a common horizontal plane, accommodatedin a lateral slot of said member, and auxiliary interlocking' Weightmembers adapted to be superposed upon the main Weight member and havingregistering end wearer notches affording collectively clearances forpassage of the sash cord or chain enroute to and from the pulleys.

2. ln a sash Weight the combination of a main Weight member with a slotextending across its top, sash cord pulleys with their axes in a commonhorizontal plane and aligned with their grooves in registry mountedWithin the slot aforesaid, and a series of aruriliary Weight membersadapted to be superposed upon the main Weight inember, each saidauxiliary Weight member being provided, for the purpose of preventingrelative displacement,"with means for interengagement with each otherand With the slot of the main Weight member, also with registering endnotches affording, collectively, elearancesfor passage of the sasl]cords enroute to and from the pulleys.

3, ln a sash weight the combination of a main Weight memberwvith a slotextending across its top, sash cord pulleys, With `their axes in acommon horizontal plane Y andy aligned with their grooves in registry,

moimted` Within the slot aforesaid, and an:

auxiliary Weight member adapted to be su perposed upon the main Weightmember, andy fording clearances for passage of the sash,y

cord or chain enroute to and` from the pulleys.

1l. ln a sash Weight the combination of a main Weight member vith aslotextendingV across its top, sash cord pulleys, with theirV axes in acommon horizontal. plane and aligned with their grooves in registry,mounted Within the slot aforesaid, and an auxiliary Weight memberadapted to be Vsuperpose-d upon the main Weight member, and Y provided,for the purpose of preventing its y displacement, with longitudinalridge for engaging the slot of the main Weight member, and also endnotches affording `clearances for passage of the sash cord or chainenroute to and from the pulleys.

5. ln a sash Weight the combination` of a main Weight member with a slotextending across its top, sash cord pulleys, with their aries in acomn'ion horizontal plane and aligned with 'their grooves in registry,mounted Within the slot aforesaid, and` an auniliary Weight memberadapted to be su perposed upon the main Weight member, andV provided,for the purpose of preventing its displacement, With a longitudinalridge fory engaging` the slot of the main Weight meme ber, andtransverse ridges for engaging re` eesses in the top of said main Weightmember, and also end notches affording clearances for passage of thesash cord or chain enroute to and from the pulleys. i,

6. ln a sash Weight of the type described the combination of a series ofauxiliary Weight members adapted to be superposed upon the main weightmember, each said auxiliary Weight member being complementarily ridgedand recessed both longitudinally and laterally for interchangeable in- Yterengagement with each other and With the main Weight member topreclude the possibility of relative displacement, and also having endnotches aording free passage for the sash cord or chain.

7 In a sash Weight of the type described the combination of a Weightmember having a lateral slot in its upper part, sash cord pulleysmounted for rotation in said slot, and screw bolts in a commonhorizontal plane forming the axles of said pulleys, the sides of theWeight members being recessed for accommodation of the heads and nuts ofthe bolts to obviate any projections beyond the Weight surface.

In testimony whereof, I have hereunto signed my name at Philadelphia,Pennsylvania, this 4th day of December, 1923.
